About me

Hi, I'm Steph a medical student at Cardiff University with a background in Biomedical Science (Bsc). I tutor Human Biology with a particular interest in Anatomy. Science has always been the core to my love of learning. I hope my passion for knowledge will encourage others to surpass their expectations and gain confidence in themselves. Whether you need revision tips or a guide through a mountain of nonsensical text, I am here to help!

About my sessions

What can I expect from sessions? Our sessions will be guided by you, but we will discuss what works best for you in advance. I will use many different techniques (acronyms, diagrams, past papers) to help you achieve your goals. Science is incredibly rewarding and I do my best to make the sessions enjoyable. Help! I’m applying to University I will gladly help with Medical School Preparation and University Applications. The dreaded UCAS application can become overwhelming, with the personal statement being the fear for many. Having been there twice myself, I have a few tips to help you out. Medical school – Where do I start? It can be hard to know what is expected from an applicant and where to find information about different courses. If you have any questions about this, please don’t hesitate to get in contact. I can help with crafting your personal statement and preparing you for interviews. I have personal experience of evaluating and partaking in medical school interviews, from which I can give you invaluable guidance. What next? Don’t hesitate to book a free Meet the Tutor Session or drop me an email if you are interested in being tutored by me. I look forward to hearing from you.

What is a Nucleotide?

A nucleotide is the basic unit that makes up DNA. A singular nucleotide is made up of x3 components:  1. A base (1 of 4 molecules = A, T, C or G) 2. 5 Carbon sugar (deoxyribose = DNA or ribose = RNA) 3. Phosphate group (forms a bond between the sugar molecules in a DNA chain = phosphodiester bo...

A nucleotide is the basic unit that makes up DNA.

A singular nucleotide is made up of x3 components: 
1. A base (1 of 4 molecules = A, T, C or G)
2. 5 Carbon sugar (deoxyribose = DNA or ribose = RNA)
3. Phosphate group (forms a bond between the sugar molecules in a DNA chain = phosphodiester bond)

Bases

There are x4 different nitrogenous bases that comprise DNA.
1. Adenosine
2. Thymine
3. Cytosine
4. Guanine
 

They come under x2 groups depending on their shape and chemical structure. 
1. x1 rings = Pyrimidines
2. x2 rings = Purines

Pyrimidines
Thymine and Cytosine are the smallest of the 4 bases. With only 1 ring in their structure.

Point to Remember!
*** In RNA, Thymine is replaced by Uracil ***

Purines
Adenosine and Guanine are the biggest of the 4 bases. Their structure contains a pyrimidine ring + a smaller 5 sided ring. Therefore making a 2 ringed structure.

Key points
A nucleotide (base + sugar + phosphate) is the building blocks for nucleic acid (DNA & RNA)

A nucleoside (base + sugar) 

Nucleotides can serve as energy carriers in the form of ATP (Adenosine TriPhosphate)

Nucleotides can aid in cell signalling e.g. cyclicAMP (cAMP)

What is the Role of the Liver during the Metabolism of Food Products?

The liver is the largest solid organ in the body as well as the largest gland. 
 

It is made up of 2 large lobes (right lobe bigger than the left lobe). Each lobe is then comprised of much smaller lobules. 
Within these lobules lies the cells of the liver, called hepatocytes. It is here that molecules are metabolised

Absorption of molecules of digestion
In the gut, protein, fats and carbohydrate are broken down into amino acids, lipids and glucose respectively. These are taken from the gut to the liver via the Portal Vein.
The liver is responsible for monitoring the levels of these molecules in the body.

E.g. Straight after a meal:

1. Storage of glucose as glycogen in the hepatocytes "glycogenesis"
2. Storage of lipids in the form of tricglycerides in the adipocytes 
3. Formation of proteins to be utlised by the skeletal muscle

In a state of hunger

1. Glygen is broken down into glucose to be used for energy "Glycogenolysis"
2. Amino acids are converted to glucose for energy during starvation "Gluconeogenesis"
3. Once all the glucose has been used up, lipids can be converted to Ketones "ketogenesis" to be utilised by the brain.

*** Glucose is the main source of energy for the brain, when glucose is depleted ketones are utilised ***
